Title: Smoking composition and method of imparting flavor thereto
IPC: A24B15/28
Filed: 1965-02-15
Abstract: A tobacco smoking composition comprises tobacco and a non-volatile, flavour-containing carbonate which decomposes upon smoking the tobacco to yield a flavourant.  The flavour containing carbonate may be, e.g. an alkylacylcarbonate, 1-menthyl cholorcarbonate or 1-menthyl linalool carbonate.  The chlorocarbonates may be prepared by reacting carbonyl chloride with suitable alcohols such as menthol, glycol, glycerol, terpene alcohols and sugars.  Such alcohols include geraniol, linalool, cinnamyl alcohol, eugenol, carvacrol (isothymol), phenylethyl alcohol and terpineol.  Chlorocarbonates so formed may be further reacted with carboxylic acid to form an alkylacylcarbonate or with a further flavour alcohol to form a di-carbonate, e.g. di-1-menthyl carbonate or 1-menthyl linalool carbonate.

Abstract: 236,613. Burgher, F. D. March 13, 1924. Variable-speed gearing suitable for vehicles comprises an arrangement by which the main shaft is reciprocated when the main clutch is disengaged and engaged, and a stop is interposed by a separate selector in the way of a returning clutch member to render the selected gear clutch operative. Driven and driving shafts 1, 2 of the speed gear are coupled so as to move longitudinally along with the movable member 20 of the main clutch. There is a lay shaft 2<a> and constant mesh pairs of toothed wheels. Each gear clutch comprises spring-separated members a, b which reciprocate with the combined main shaft 1, 2, the member a being fixed and the member b being adapted to be held against returning to the left as the main clutch is let in, by one of a set of sliding stops e. The member b of the direct-driving clutch 12 is splined on the end of the driving-shaft 2, and, when the direct, drive is in use, the toothed gearing is at rest. For two reduced speeds and reverse, one of the clutches 14, 15, or 16 is operated simultaneously with the operation of a clutch 13 for actuating the lay shaft. The stops e are normally held out of action by springs f and are thrust down into operative position in proper combinations by cams g on a shaft 26 turned by the selector.

Title: Improvements in or relating to slub catchers for yarn
IPC: B65H63/06
Filed: 1931-03-04
Abstract: 370,592. Yarn clearers. ECLIPSE TEXTILE DEVICES, Inc., Elmira, New York, U.S.A. March 4, 1931, No. 6688. Convention date, March 4, 1930. [Class 120 (ii).] In a device for catching slubs in yarn comprising a stationary member having a recess across which the edge of a movable member extends to define a closed eye the movable member is pivotally mounted on an intermediate member which is itself pivotally mounted on the stationary member. A plate A, having an offset bracket A<1> for mounting on the frame of a winder has a cam edge A<4> leading to a notch A<3> for the yarn. A flat plate C is pivoted at AC to the plate A, the movement of the plate C being limited by a screw C<1> moving in a slot A<8> in the plate A. A movable plate B with a recess, an edge B3 of which combines with the recess A<3> to form a closed eye E is mounted on the lever C by a pivot BC which also serves to connect a strengthening plate B<5> to the movable plate. The pivot BC passes through an enlarged hole A<7> in the plate A so that the pivoting of the plate C about the pivot AC to adjust the size of the eye is not interfered with. The movement of the member B to adjust the size of the eye is substantially transverse to the eye defining edge B<3> and to the movement about the pivot BC for opening the eye for threading purposes. The plates B, B<5> are connected by a rivet B<6> and separated by a spacing sleeve B<7>. The member B is supported in the normal position by the strengthening plate B<5> resting on a projection A<5> on the plate A. This projection A<5> has an inwardly tapering surface A<6> so that the arrival of a slub at the eye the yarn is pushed against the sharp edge B<3> of the movable member and cut. The yarn is rethreaded, after breaking out a slub and rejoining, by drawing it between the overlapping cam edges on the fixed and movable plates. A modified form of slub catcher suitable for use with a spooler has no strengthening plate and is so arranged that to open the eye for threading the movable member is moved against the action of a spring instead of against gravity as in the first modification. The projection A<5> is also dispensed with and the converging slub guiding surface is provided directly on the fixed plate.

SCARPA ET MAGNANO, Via Fiume, Savona, Italy. March 4, 1930, No. 7079. Convention date, March 6, 1929. [Class 37.] A current transformer having an iron core M1 surrounding a bushing through which passes the conductor P1 is adapted also to measure voltage by providing a primary winding T1 connected between earth and a condenser coating C1 placed on the bushing and having capacity with respect to the conductor Pl. The winding T1 thus carries a capacity current proportional to the voltage. As shown, a second similar transformer is placed on the bushing of a second conductor P2 of the same phase and connected by a switch I to the conductor P1. The secondary windings S1, S2 are connected through switches 11 .. 14, k, and choking coils R1, R2 to an ammeter A and voltmeter V. With the switch k on the contact 10, switches I, 11 open, and switches 12, 13, 14 closed, the voltmeter V indicates the voltage between the conductor P2 and earth. Similarly by opening the switch 12 and closing the switch 11, the voltage of the conductor P1 is measured. By opening the switches 13, 14 and placing the switch k on the contact 9 the vectorial sum of these two voltages is measured, enabling the instrument to be used for synchronizing. With the switch I closed, switches 11 .. 14 closed, and the switch k on the contact 10, the currents induced in the secondary windings S1, S2 by the capacity currents in the windings T1, T2 are added in the circuit of the voltmeter V but annul one another in the circuit of the ammeter A. The currents induced by the current in the conductors P1, P2 are added in the circuit of the ammeter A but annul one another in the circuit of the voltmeter V. Current and voltage are thus separately measured. The apparatus may be modified for measuring power or frequency or for the operation of relays for remote control.

Abstract: 619,866. Reversing gearing; clutches. FAIRFIELD SHIPBUILDING & ENGINEERING CO., Ltd., and DAVIS, A. W. March 7, 1946, Nos. 7123 and 18334. [Class 80 (ii)] Reversing gearing for ship propulsion comprises a double hydraulic coupling 42, 43, operable to couple a high-speed driving shaft 10 to a low speed propeller shaft 11 through either an astern pinion 30 or a double reduction layshaft gearing 15, 32, 33, 34. The astern pinion shaft 13 and the primary ahead pinion 15 are arranged as co-axial extensions of the driving shaft 10, the pinion 15 having a central quill shaft 12 directly connected to the two driving members 26, 27 of the double coupling. A sliding dog clutch member 22 connects a clutch member 20 on the driving shaft 10 with a similar member 16 on the quill shaft 12 at all times and is selectively engageable with a clutch member 17 rigid with the ahead pinion 15 to byepass the ahead fluid coupling for normal running. Spring loaded friction pads 58 are provided on the members 17 to assist in the shock free engagement of the dog teeth. The double hydraulic coupling comprises the two driving members 26, 27 rigid with the shaft 12 and the two driven members 28, 29 rigid respectively with the ahead and astern pinions, oil for the operation of the couplings being supplied along the hollow shafts and being exhausted from the inoperative coupling. Two slide valves 51, 52, selectively control the outlet of oil from the couplings and are moved axially by the rotation of a camplate 54 which engages the slots 55 in the bars 53 connecting the valves. Thus by actuation of the valves 51, 52 and the clutch sleeve 22 the gearing provides double reduction ahead positive drive for normal use, double reduction ahead through the fluid coupling for manoeuvring, and single reduction reverse through a fluid coupling. According to the first Provisional Specification the fluid coupling may be either electric, hydraulic or pneumatic.
